Benefits of technology

[0006] It is therefore an object of the present invention to provide a control system and method, which ensures satisfactory detection of biometric information for validating a user.

Problems solved by technology

This system is, however, disadvantageous in that the doors may be unlocked and the engine may be started even if the portable device is used by an unauthorized vehicle user.
This system thus restricts vehicle door unlocking and engine starting by an unauthorized user.
The surface of the glass will be stained or blurred, particularly when the finger or a part of a user body is required to touch the glass for biometric detection.
This causes poor detection of the biometric information of the user.

Embodiment Construction

[0013] Referring to FIG. 1, a control system is applied to a vehicle as a smart entry system. The control system includes a portable device (electronic key) carried by a vehicle user, a sensor device 3 provided on a driver-side door to optically detect biometric information of the user and a vehicle-mounted control device 5 for controlling an electronic control unit for a vehicle door (door ECU) 7 and an electronic control unit for a vehicle engine (engine ECU) 9. The sensor device 3 may detect a finger print of the user as the biometric information of the user. The control device 5 receives identification information (ID code) from the portable device 1 through radio communication and receives the biometric information from the sensor device 3 to check whether the user is an authorized person. The control device 5 outputs a door control command and an engine control command to the ECUs 7 and 9, respectively, if the user is validated as the authorized person.

Abstract

An entry control system includes a portable device carried by a vehicle user and a biometric sensor attached to a vehicle door. The biometric sensor includes a CCD camera and a shutter. The shutter is moved to uncover the CCD camera only when the portable device is validated. After the biometric sensor detects the biometric information based on a finger print image of the user, the shutter is moved again to cover the CCD camera. Each time the shutter moves, a brush cleans the CCD camera. The vehicle door is enabled to be opened only when the user is validated based on the biometric information.

Description

CROSS REFERENCE TO RELATED APPLICATION [0001] This application is based on and incorporates herein by reference Japanese patent application No. 2004-264122 filed on Sep. 10, 2004. FIELD OF THE INVENTION [0002] The present invention relates to a control system and method, which validate a user based on biometric information. BACKGROUND OF THE INVENTION [0003] Various remote control systems are now in use. In one system such as a smart entry system, a portable device (electronic key) carried by a vehicle user transmits a response signal in return to an interrogatory signal periodically transmitted from a vehicle. This response signal includes identification information therein. If the portable device is validated based on the identification information, vehicle doors are unlocked and a vehicle engine starting is enabled. This system is, however, disadvantageous in that the doors may be unlocked and the engine may be started even if the portable device is used by an unauthorized vehicl...
